Guangzhou is an important transportation hub situated at the heart of the Pearl River Delta, so emissions reduction is a big challenge. However, monitoring data showed that the air quality has steadily improved because of its great efforts in four areas: 1) reducing the use of coal by adjusting the energy structure and establishing “no coal burning zones”; 2) promoting green public transportation, such as using LPG buses and taxis, adopting more stringent vehicle emission standards; 3) reducing dust; and 4) controlling oil fumes.
